Benefits of technology

The present invention is a new technology for back frames and backlight systems of panel display devices. It reduces material and mold costs by using a skeleton structure and heat-dissipating material for the main splicing elements. The main splicing elements are designed to simplify the structure of back frame molds, saving money on manufacturing. The back frame is also easy to assemble with a front frame and panel, as it has hooks on one of its sides. Overall, this technology helps to manage costs and achieve improved heat dissipation.

Problems solved by technology

As shown in FIG. 1, a back frame 10 of known technique is usually made of a monolithic structure, manufactured by metal stamping or plastic inject molding techniques so that back frame 10 consumes more material and results in high material cost.
In addition, a large-sized back frame 10 usually requires larger stamping equipments and larger molds with complex structure, thus, a higher cost.

first embodiment

[0055]Also refer to FIG. 3. back frame 23 comprises: a first main splicing element 261 and a second main splicing element 262. One end of the first main splicing element 261 is spliced with one end of the second main splicing element 262, and the other end of the first main splicing element 261 is spliced with the other end of the second main splicing element 262 to form the main frame 27 of the back frame 23. Both the first main splicing element 261 and the second main splicing element 262 are made of aluminum or galvanized steel. In the present embodiment, both the first main splicing element 261 and the second main splicing element 262 are L-shaped.

second embodiment

[0056]Also refer to FIG. 4. the back frame 23 comprises: a first main splicing element 281, a second main splicing element 282 and a third main splicing element 283. The first main splicing element 281, the second main splicing element 282 and the third main splicing element 283 are spliced to form the main frame 27 of the back frame 23. The first main splicing element 281, the second main splicing element 282 and the third main splicing element 283 are all made of aluminum or galvanized steel. In the present embodiment, the first main splicing element 281 is L-shaped, and both the second main splicing element 282 and the third main splicing element 283 have a long strip shape.

[0057]In addition, the back frame 23 can also comprises two auxiliary splicing elements disposed inside and spliced with the main frame 27.

[0058]The following uses four main splicing elements and two auxiliary splicing elements to describe the back frame 23 of the panel display device 20 of the present inventi...

fourth embodiment

[0059]Referring to FIG. 5, FIG. 5 is a schematic view showing the structure of the panel display device according to the present invention. As shown in FIG. 5, in the instant embodiment, the back frame 23 comprises: a first main splicing element 231, a second main splicing element 232, a third main splicing element 233, a fourth main splicing element 234, a first auxiliary splicing element 235, a second auxiliary splicing element 236 and support frames 2371, 2372, 2373, 2374, 2375, 2376, 2377. The first main splicing element 231, the second main splicing element 232, the third main splicing element 233 and the fourth main splicing element 234 are spliced in a head-to-tail manner to from the main frame 27 of the back frame 23. The first auxiliary splicing element 235 and the second auxiliary splicing element 236 are auxiliary splicing elements, disposed inside the main frame 27 and spliced with the main frame 27.

[0060]Specifically, one end of the first main splicing element 231 is sp...

Abstract

The present invention provides a panel display device, back frame and manufacturing method for back frame. The back frame includes at least two main splicing elements forming back frame, the at least two main splicing elements including main splicing element for disposing light source, wherein light source is disposed on a surface of side wall of main splicing element bended upward for light source disposition, downward hooks are disposed on the other surface of side wall away from light source, main splicing element with light source has a first heat-dissipation capability, and remaining main splicing elements of the at least two main splicing elements without light source have a second heat-dissipation capability, first heat-dissipation capability is better than second heat-dissipation capability. As such, the present invention can reduce material and mold costs as well as better heat-dissipation and easy assembling of front frame and panel.
